Need replacement Poles for Towsure Insignia Awning

After the horrible rain last week, two of the poles on my Towsure Insignia awning buckled and broke, As its an old awning Towsure dont have any replacements, I need a vertical corner pole and a Horizontal pole that goes across the front, number 6 and number 8 on the attached schematic. Does anyone have any idea where I can get replacement poles, or if I can use poles from a later model to replace?

thanks in advance,  Rob
